Damn. I normally only use ista , I’m not sure how capable the autel is but you need to try the synchro with ista + Icom

I wouldn’t buy anything just yet. Can you even communicate with the CAS?

Yes, I have communication with the cas

Remove negative battery lead wait ten mins Then reconnect try again with autel if its original dme and cas it should synchronise

You should try this first. If not, then

Perform cap discharge
While that’s going on, pull spark plugs and make sure they’re not fouled, if they are, clean em.
Then reconnect battery cable ends (+ first - last)
Go into dme and reset it ,
Go into CAs and reset it
Then perform sync

If that don’t work then I’d be questioning the dme and/or CAs’ originality because when you go to start the car,.
The CAs and the dme have to be on the same page . Like a secret handshake. If the dme goes to greet the CAs with a thumbs up and the correct response is a peace sign, but the CAs throws the middle finger, then you won’t start. The CAS seems to know your key, because the starter is engaging. But while that starter relay is energized, someone is throwing the wrong signs to each other. And it’s more likely the CAS .

I’m also only speculating,

I'm sure you're right.

I've been finding out about my autel scanner's ability to do the alignment and apparently it's not capable. In this vehicle model the option of aligning is not available.

Then inpa is not capable either. I only have the option to use ista for what I have found. I have searched even more and found that I can use ista with my j2534 from autel. But I really don't know how ista works. Is my first time.

I must download ista and ista / p and install it on my pc. Then I also read that I must subscribe on the bmw website for one day to be able to access and perform the procedure.

Do you know any simpler way to do this or is that the only way?

A simpler way would be to find someone with ista or autologic who’s willing to go to you , where you located ?

Or maybe tow your car through your insurance , and have the dealer or a euro shop handle it. But if you can afford to have your car down for a bit, then you can have success with ista/d and a K+Dcan cable. You don’t need ista/p to sync cas-dme. Use ista/d. Don’t use ista/p unless you have icom. A genuine factory icom is relatively inexpensive. And a good investment if you DIY and/or plan to own more bmws.

Let me know your location. I have an extra cable

But the engine cranks, which should mean that the CAS is allowing the starter to engage. Which makes me think synchro is ok

No it doesn't .... these will crank if not aligned do as i say .. LET CAR DISSIPATE WITH NO BATTERY POWER REFIT TERMINAL AND TRY AGAIN WITH AUTEL

hi bud.

I was entertained with other cars today and did not touch the car all day.

Going back to the matter hehe. well I have a K + CAN K + DCAN cable wl which I use to connect with inpa. I don't know if that would work? .

I'm in Kissimmee Florida.

Pd. Yes. I want to continue working with bmws. I would like to make tools. at least the necessary ones and start trying not to be so expensive

I already tried to leave the car for more than 20 minutes without a battery bro.

Also try to make a discharge capacitor. And it didn't work out.

The issue is that autel does not support synchronization ews "4".

There is no alignment option. You can only reset the modules. there is even a video of an autel consultant on youtube that the guy says that in certain cars even after an update to the modules antitampering codes can occur and he says that it should be corrected with ista and ista / p.

In the first image you can see the options that my scanner gives in that car and the option of alignment is missing. and in the second image you see the complete options for other cars

Refit the battery terminal Then On your autel go into .. CAS.. then Special Functions ....then CAS DDE DME ALIGNMENT

E90 HAS CAS 2 OR 3 NOT EWS

Possibly trying to access stuff the vehicle doesn't have . in DDE DME you need to go into cas special function

[jimmyhgr]

I have found information from people like you who claim that e90 has no ews. Just cas. and I'm sure you have more knowledge than me in this.

But if so, because inpa says that it is of type ews4 and that it is blocked. believe me that I have looked everywhere for options that allow me to align with autel within the dme does not appear any that allows me to align.

I really don't know what to do anymore. I'm downloading ista/d to try.
